Introduces `std.builtin.Panic` which is a complete interface for

`std.debug.SimplePanic` and let the user choose, or make their own.

0d00c733de std.os.linux: extend rtattr.type to support IFA_* 
This is a breaking change which updates the `rtattr.type` from `IFLA` to
`union { IFLA, IFA }`. `IFLA` is for the `RTM_*LINK` messages and `IFA`
is for the `RTM_*ADDR` messages.

8d76c02f9a uefi: erroneous alignment check in pool_allocator 
Fixes #21446

Both UefiPoolAllocator and UefiRawPoolAllocator were
passing the value of `log2_ptr_align` directly to
`mem.alignAllocLen` which expects a alignment value.

Both of these calls to `mem.alignAllocLen` are pointless
and the result of the alignment both always true, and
was thrown away anyway.

I have removed these calls entirely.

ffd071f558 fix IB in fifoToOwnedArrayList 
memcpy requires non-overlapping arguments.

fifo.realign() handles this case correctly and tries to provide an
optimized implementation.

This probably wasn't hit in practice, as, in a typical usage, fifo's
head is not advanced.

Improve efficiency of buffered_reader. (#21256) 
The previous implementation of buffered_reader always reads from the
unbuffered reader into the internal buffer, and then dumps the data onto
the destination. This is inefficient, as sometimes it's possible to read
directly into the destination. The previous strategy generates more
memory copies and unbuffered reads than necessary.

d1901c744c std.Target: Remove Cpu.Arch.dxil and ObjectFormat.dxcontainer. 
See: https://devblogs.microsoft.com/directx/directx-adopting-spir-v

Since we never hooked up the (experimental) DirectX LLVM backend, we've never
actually supported targeting DXIL in Zig. With Microsoft moving away from DXIL,
that seems very unlikely to change.

509639717a std.equalRange: Compute lower and upper bounds simultaneously 
The current implementation of `equalRange` just calls `lowerRange` and `upperRange`, but a lot of
the work done by these two functions can be shared. Specifically, each iteration gives information about whether the lower bound or the upper bound can be tightened. This leads to fewer iterations and, since there is one comparison per iteration, fewer comparisons.
Implementation adapted from [GCC](519ec1cfe9/libstdc%2B%2B-v3/include/bits/stl_algo.h (L2063)).
This sample demonstrates the difference between the current implementation and mine:

```zig
fn S(comptime T: type) type {
    return struct {
        needle: T,
        count: *usize,

        pub fn order(context: @This(), item: T) std.math.Order {
            context.count.* += 1;
            return std.math.order(item, context.needle);
        }
        pub fn orderLength(context: @This(), item: []const u8) std.math.Order {
            context.count.* += 1;
            return std.math.order(item.len, context.needle);
        }
    };
}
pub fn main() !void {
    var count: usize = 0;

    try std.testing.expectEqual(.{ 0, 0 }, equalRange(i32, &[_]i32{}, S(i32){ .needle = 0, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 0, 0 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 0, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 0, 1 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 2, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 2 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 5, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 3 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 8, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 5, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 64, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 6, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 100, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 8, 8, 8, 15, 22 }, S(i32){ .needle = 8, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 2 }, equalRange(u32, &[_]u32{ 2, 4, 8, 16, 32, 64 }, S(u32){ .needle = 5, .count = &count }, S(u32).order));
    try std.testing.expectEqual(.{ 1, 1 }, equalRange(f32, &[_]f32{ -54.2, -26.7, 0.0, 56.55, 100.1, 322.0 }, S(f32){ .needle = -33.4, .count = &count }, S(f32).order));
    try std.testing.expectEqual(.{ 3, 5 }, equalRange(
        []const u8,
        &[_][]const u8{ "Mars", "Venus", "Earth", "Saturn", "Uranus", "Mercury", "Jupiter", "Neptune" },
        S(usize){ .needle = 6, .count = &count },
        S(usize).orderLength,
    ));

    std.debug.print("Count: {}\n", .{count});
}
```
For each comparison, we bump the count. With the current implementation, we get 57 comparisons. With mine, we get 43.

With contributions from @Olvilock.
This is my second attempt at this, since I messed up the [first one](https://github.com/ziglang/zig/pull/21290).

812557bfde std: Restore conventional compareFn behavior for binarySearch 
PR #20927 made some improvements to the `binarySearch` API, but one
change I found surprising was the relationship between the left-hand and
right-hand parameters of `compareFn` was inverted. This is different
from how comparison functions typically behave, both in other parts of
Zig (e.g. `std.math.order`) and in other languages (e.g. C's `bsearch`).
Unless a strong reason can be identified and documented for doing
otherwise, I think it'll be better to stick with convention.

While writing this patch and changing things back to the way they were,
the predicates of `lowerBound` and `upperBound` seemed to be the only
areas that benefited from the inversion. I don't think that benefit is
worth the cost, personally. Calling `Order.invert()` in the predicates
accomplishes the same goal.

e17dfb9da0 std.http.WebSocket: Make 'upgrade: websocket' check case-insensitive 
I've seen implementations in the wild that send 'Upgrade: WebSocket',
which currently fails the handshake.

From https://datatracker.ietf.org/doc/html/rfc6455:

"If the response lacks an |Upgrade| header field or the |Upgrade| header
field contains a value that is not an ASCII case-insensitive match for
the value "websocket", the client MUST _Fail the WebSocket Connection_."
